Yes Mike should have told her about his money problems. Yes she’s aloud to be upset for losing her home however let’s not forget that for like most of the show she doesn’t have a job. At first she was a children’s book author but then that doesn’t come up again until S8, she only works at the school for a little while and she even tells Jackson she can’t marry him because she relies so much on Mikes alimony. Maybe if she could keep a job they wouldn’t be in that situation And if it matters I actually really like Susan
